Our problem was a glass cup. Changed cup to opaque cup and it worked ok, (optical sensor ?)

Lift the reservoir, then reseat it. This will clear the prime message. If it repeatedly comes back then your machine is dead. If in the year warranty, call Keurig they will ship you a replacement. A common Keurig problem.

Some of the case is held with compression fittings, which you really have to be careful not to break. A long and very thin flat head screwdriver and some patience can probably get you there.

Try digging out the puncturing needle on the top of the cup mechanism with a safety pin. Often, the pin gets build up from sugars & starches from non-coffee cups. If that doesn't work, try running a tank of pure white vinegar through your machine. That will dissolve any build up from hard water or lime scale.

ADD WATER!!! Or is there some other problem that you don't describe, or something I am not understanding?

I'm not completely certain what the problem is because it's not displaying your whole subject (it get's cut off after electricity to...). However, if it is solving the problem by moving it out of the kitchen, it's likely that the problem that the circuit is overloaded. Coffee makers have a large current draw, as do many other kitchen appliances. If you plug too many of them into the same circiut and then turn them on, you will put too high a drain on the circuit and it will cause the the current to become unreliable and then, eventually, through the braker or blow the fuse to protect the wiring in the wall (to keep it from catching fire). If this is the case, you need an electrician to run another circuit or remove some appliances from your kitchen.

PLugged ports. Needs cleaning.

Prime is the action whereby the water is sucked up from the reservoir (water supply) into the heating compartment.

Mine would only very loudly pump a partial cup after about two years of use. I tried everything, including descaling. Even held my mouth different ways. I took it apart three times, the last time intending to glue all the rubber hoses. By accident I discovered a plastic "filter" in the intake line just below the water reservoir. I removed it, cleaned it out on both sides with a toothbrush, put it back in, and now it works like new. The filter is easy to get to if you take the bottom metal plate off: 5 screws for that, then two screws in the filter unit directly under the reservoir. You get to it from underneath the coffee maker. Pull the black cover back to expose the plastic hose, then pull the black filter out.
It is easier to do than to describe.
I have not seen this fix anywhere on the net, but I can verify that it works.
